If you can find this seasonal, grab it while you can. Harvest Moon was not what I was expecting and turned out to be one great beer.
This was not an over-spiced pumpkin pie ale. Blue Moon's seasonal is an amber colored ale first which is balanced with the warmness of apple, pear, vanilla and hints of pumkin (If it was not on the label I probably would not have been able to identify the pumpkin flavor). There also seems to be some clove or other warm spices in the back ground.
What was very surprising was how light and proportioned this beer is. This drank a lot like a Bass Ale as the flavors were mellow and not heavy.
Find Harvest Moon and try it before this seasonal goes away.
